Overall, this is a great watch!The sleek and slender design makes it not only comfortable to wear but also nice enough to wear on formal occasions or with business attire. I have had problems in the past with silicon banded watched because my sensitive skin easily becomes irritated; however, this band breathes so well that, even when I sleep with the band on, I am comfortable and have no problems/reactions. Further, I have Issues with swelling that goes up and down throughout the day, requiring me to adjust the tightness of the band throughout the day. This is very easy to do with this watch! It is so simply to adjust that it takes almost no effort.The battery life on the watch lasts a very long time. Even when I have the watch on 24/7, it last nearly a week with everything enabled. This is especially important to me since I have to wear the watch when I am sleeping, so there is not always a convenient time to charge it. When I do need to charge the watch, it charges quickly – usually in less than an hour – and conveniently can be charged by plugging it into my laptop while I am working.I originally got a fitness watch because I have POTS which causes me to have a high heart rate and low blood pressure and requires that I monitor both of these, especially my heart rate which is hard for me to feel/be aware of. As such, the watch’s ability to track my heartrate constantly and accurately is very important to me. I was originally worried, since I have a small wrist, that the monitor might have trouble staying where it needed to in order to get accurate readings; however, the watch has proven to be very accurate, even while I am sleeping. The only time I get inaccurate heart rate readings is when I bend my wrist too far so that the watch isn’t fully touching my wrist anymore (which is not a problem with the watch). As for blood pressure, wrist readings are usually wildly inaccurate for me, so I was pleasantly surprised to find that, compared to the blood pressure cuff that I keep at home for measuring on my arm, the watch is generally 10-15 points high consistently and has actually been exactly the same on a few occasions. Not only is this a fairly small margin of error, it is consistent. As such, I can use the watch to estimate my current BP by simply subtracting 10 from whatever reading it gives me.Finally, I had never used a watch to get notifications from my phone before because I had worried that it would wear down the battery (as mentioned above, that is NOT a problem) and because I have had friends with smartwatches that have very disruptive notifications; however, when I hesitantly decided to try notifications with this watch, I found the notifications to be useful and not disruptive at all. The vibration is noticeable enough to catch my attention without being too loud, so it does not pose a problem even in meetings, and I don’t even need to bother turning notifications off to sleep.This is a seriously great watch and I highly recommend it!
